Add Text to Crypt-Requests for Keys

This is suggested text to add to crypto-requests for keys, based on what the key derivation is.

My general suggested format is:

```
Another device is requesting a [public|private] key from this device with this derivation:

[derivation]

[derivation explanation]

[if there is a description:]

The device has included the following description to explain their request:

[description]
```

My suggested derivation explanations are:

**48'/0'/0'/2'**
This requests a [public|private] key for use in a multisig, using the best-practice Segwit methodology.

**84'/0'/0'**
This requests a single-sig [public|private] key, using the best-practice Segwit methodology.

**48'/0'/0'/1'**
This requests a Nested Segwit [public|private] key for use in a multisig. This style of key is outdated, but still in use on some older wallets.

**49'/0'/0'**
This requests a single-sig [public|private] key. This style of key is outdated, but still in use on some older wallets.

**45'** or **48'/0'/0'/0'**
This requests a [public|private] key for use in a multisig. It is a request for a very outdated Legacy key rather than a modern Segwit key.

**44'/0'/0'**
This requests a single-sig [public|private] key. It is a request for a very outdated Legacy key rather than a modern Segwit key.

**Master**
This requests a [public|private] Master Key for your seed. Be aware that this will provide [watch-only access|total access] to your entire HD wallet.

**86'/0'/0'**
This requests a single-sig [public|private] key using the new Taproot protocol. Be aware that this is a very new methodology and there may be some dangers associated with its usage as a result.
